Calculate the ph of a buffer solution that contains 0.25 m, Ask an Expert

Academics

1) If you mix equal concentrations of reactants and products, in which direction would the following reaction proceed. Right or left?

H2SO4(aq) + NH3(aq) <--> NH4^+ (aq) + HSO4^- (aq)

(I'm guessing the arrow is double sided...don't know if that'll effect the answer?)

2) What is the pH of a 1.00 M HF solution? The Ka for HF is 7.2 x 10^-4. Please show your work for how you got this.

3) Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5COOH) and 0.15 M sodium benzoate (C6H5COONa). Ka= 6.5 x 10^-5 for benzoic acid. Please show your work for how you got this.
